Abstract

A support structural member and a display device. The support structural member includes: a support frame, having a screen body support surface, in which the support frame includes a first sliding support member and a second sliding support member arranged opposite to each other, and the first sliding support member and the second sliding support member are movably connected in a first direction; a driving portion, including a first driving mechanism, in which the first driving mechanism is configured to drive the first sliding support member and the second sliding support member to move relatively to each other in the first direction to drive the first sliding support member and the second sliding support member approach to or far away from each other.

First claim

What is claimed is:

1 . A support structural member for a display device, comprising:
a support frame, comprising a screen body support surface, wherein the support frame comprises a first sliding support member and a second sliding support member arranged opposite to each other, and the first sliding support member and the second sliding support member are movably connected in a first direction; a screen body connecting member; and a driving portion, comprising a first driving mechanism and a second driving mechanism, wherein the first driving mechanism is configured to drive the first sliding support member and the second sliding support member to move relative to each other in the first direction to drive the first sliding support member and the second sliding support member to approach or withdraw from each other, the second driving mechanism is configured to drive the screen body connecting member, and a linkage mechanism connects the first driving mechanism with the second driving mechanism; wherein the driving portion is arranged at a side of the support frame facing away from the screen body support surface, and the support frame further comprises: a main body support member, each of the first sliding support member and the second sliding support member is movably connected to the main body support member in the first direction, and the first driving mechanism is configured to drive the first sliding support member and the second sliding support member to simultaneously move relative to the main body support member.

2 . The support structural member according to claim 1 , wherein the screen body connecting member is arranged at the side of the support frame facing away from the screen body support surface, and the second driving mechanism is configured to:
drive the screen body connecting member to move in a same direction as the second sliding support member moves, drive the screen body connecting member to move in a same direction as the first sliding support member moves, or drive the screen body connecting member to move in a same direction as both the second sliding support member and the first sliding support member move.

3 . The support structural member according to claim 2 , wherein the screen body connecting member further comprises:
a first screen body connecting member, and the second driving mechanism is configured to drive the first screen body connecting member to move in the same direction as the second sliding support member moves.

4 . The support structural member according to claim 3 , wherein the first driving mechanism is configured to:
drive the first sliding support member to move relative to the main body support member at a first velocity V 1 ; and drive the second sliding support member to move relative to the main body support member at a second velocity V 2 , and the second driving mechanism is configured to drive the first screen body connecting member to move relative to the main body support member at a third velocity V 3 , and V 3 =V 1 +2V 2 .

5 . The support structural member according to claim 2 , wherein the screen body connecting member further comprises:
a second screen body connecting member configured to drive the second screen body connecting member to move in the same direction as the first sliding support member moves.

6 . The support structural member according to claim 5 , wherein the first driving mechanism is configured to:
drive the first sliding support member to move relative to the main body support member at a first velocity V 1 ; and drive the second sliding support member to move relative to the main body support member at a second velocity V 2 , and the second driving mechanism is configured to drive the second screen body connecting member to move relative to the main body support member at a fourth velocity V 4 , and V 4 =2V 1 +V 2 .

7 . The support structural member according to claim 2 , wherein the screen body connecting member further comprises:
a first screen body connecting member and a second screen body connecting member, and the second driving mechanism is configured to: drive the first screen body connecting member to move in the same direction as the second sliding support member; and drive the second screen body connecting member to move in the same direction as the first sliding support member moves.

8 . The support structural member according to claim 7 , wherein the first driving mechanism is configured to:
drive the first sliding support member to move relative to the main body support member at a first velocity V 1 ; and drive the second sliding support member to move relative to the main body support member at a second velocity V 2 , and the second driving mechanism is configured to drive the first screen body connecting member to move relative to the main body support member at a third velocity V 3 ; and drive the second screen body connecting member to move relative to the main body support member at a fourth velocity V 4 , and V 3 +V 4 =2(V 1 +V 2 ).

9 . The support structural member according to claim 7 , wherein the linkage mechanism configured to:
drive the second driving mechanism to move the first screen body connecting member in the same direction as the second sliding support member moves when the first driving mechanism drives the second sliding support member to move; and drive the second driving mechanism to move the second screen body connecting member in the same direction as the first sliding support member moves when the first driving mechanism drives the first sliding support member to move.

10 . The support structural member according to claim 2 , wherein the first driving mechanism further comprises:
a first threaded rod, a first sliding block and a second sliding block, the first threaded rod is rotatably connected to the main body support member, the first threaded rod comprises a first segment and a second segment with opposite threaded helical directions, the first sliding block is threadedly connected to the first segment of the first threaded rod, the first sliding support member is connected to the first sliding block, the second sliding block is threadedly connected to the second segment of the first threaded rod, the second sliding support member is connected to the second sliding block, and the first threaded rod drives the first sliding block and the second sliding block to move in the first direction when the first threaded rod rotates relative to the main body support member.

11 . The support structural member according to claim 10 , wherein the second driving mechanism further comprises:
a second threaded rod and a third sliding block, the second threaded rod is rotatably connected to the main body support member, the third sliding block is threadedly connected to the second threaded rod, the screen body connecting member is connected to the third sliding block, and the second threaded rod drives the third sliding block to move in the first direction when the second threaded rod rotates relative to the main body support member.

12 . The support structural member according to claim 11 , wherein the second threaded rod further comprises:
